The rear mounted disc mower is intended to mow green fodder: grass, alfalfa and such on
permanent grassland (pastures), on crop fields without rocks, and to form loose rows of cut
fodder. The pasture or field being mown should be even, best if prepared by rolling. In
the event of a majority of tall grass the first and second mowing should be done at a height of
60 - 70 mm, while with a majority of short grasses at a height of 50 mm. The last mowing
should be done a little higher - at 70 - 80 mm from the ground.
2.
A mower with the crop scarifier/rollers is equipped with the „Perfect Cut” cutterbar or
the optional „Heavy Duty” cutterbar.
The rear mounted disc mower with crop scarifier/rollers is intended to mow green fodder:
grass, alfalfa and such on permanent grassland (pastures), on crop fields without rocks, and to
form loose rows of cut fodder. As a result of the passing of the layers of the green fodder
through the flails or rollers the grass stems are broken and a layer of wax is removed. This
facilitates and speeds up the drying process of the fodder by approximately 30 to 40%. The use
of rollers is especially recommended when mowing legumes such as alfalfa. Rollers are
particularly recommended for mowing grass legume such as alfalfa. The pasture or field being
mown should be even, best if prepared by rolling. This is especially true of mowers with rollers
as they tolerate rocks with a diameter of a few centimeters. If a larger stone is picked up stop
and remove it as it could cause damage of the discs. With a majority of tall grasses the first and
second mowing should be done at a height of 6 - 7 cm, while with a majority of short grasses at
a height of 5 cm. The last mowing should be done a little higher - at 7 - 8 cm from the ground.
